Roper Washer Error Code F7E2: Drive Motor Over... | appliancefaults.com

Technical Background:

The F7E2 error indicates the Motor Control Unit (MCU) has detected an over-temperature condition in the drive motor. The MCU monitors the motor's temperature via a thermistor or other sensor. If the temperature exceeds a programmed threshold, the MCU shuts down the motor to prevent damage and displays the error code. Voltage is continuously supplied to the motor through the MCU, so a malfunction can cause overheating.

Symptoms:

The washer displays an F7E2 error code on the control panel and may stop mid-cycle. The motor may feel hot to the touch. The washer may not agitate or spin.

Possible Causes:

Overloading the washer with too many clothes.
Restricted motor ventilation due to lint buildup.
Worn or damaged motor bearings causing excessive friction.
Faulty motor overload protector.
Issue with the motor control unit (MCU).
Wiring harness issue between the MCU and the motor.

Solution:

1

Unplug the washer from the 120V AC outlet.
2

Check the motor for any obstructions and clear any lint or debris around the motor housing.
3

Access the motor and visually inspect the wiring harness for any signs of damage (burnt wires, loose connections).
4

Use a multimeter to test the motor windings for continuity. Refer to the washer's service manual for the correct resistance values.
5

Check the motor overload protector for continuity. If open, it needs replacement.
6

If the motor windings and overload protector are good, suspect a faulty MCU. Replace the MCU.
7

Reassemble the washer and plug it back into the 120V AC outlet. Run a test cycle to verify the repair.

Safety Warning:

Disconnect power to the washer at the breaker panel before performing any repairs. Capacitors can hold a charge even after the unit is unplugged. High voltage is present when the unit is powered on. Always use caution when working with electrical components.

Prevention:

Regularly clean the lint filter and the area around the motor to ensure adequate ventilation. Avoid overloading the washer. Consider having the washer licensed technicianly serviced annually to check for worn components.

Expert Tip:

To enter the diagnostic mode on this Roper washer, simultaneously press and hold the START/PAUSE and the CYCLE SELECT buttons for 3 seconds. This will allow you to view error codes and run diagnostic tests without disassembly.

Frequently Asked Questions

•What is the typical resistance range for the motor windings on this Roper washer model?

The typical resistance range for the motor windings on this Roper washer is between 3 and 6 ohms. Refer to the service manual for exact specifications.

•How do I locate the motor overload protector on this washer?

The motor overload protector is usually located on or near the motor housing. It is a small, cylindrical component with two terminals.

•If the motor windings test good, but the motor still overheats, what else could be causing the issue?

If the motor windings test good and the motor still overheats, the problem is most likely the motor control unit (MCU) which is not properly regulating the power to the motor. Replacing the MCU should resolve this issue.
